True, converting it to a solid does allow it to mesh, but the facet faces remain and limit the ability of the mesh to propagate as it would on a 'smooth' surface. From previous attempts, unless an extremely fine mesh was defined, the outer facet triangular faces remained unchanged while the inner geometry followed the mesh size specified.
When meshing, the only way I currently know how to remedy this is by assigning virtual cell regions. The mesh, BC definitions, and Fluent solution worked fine. Although this is a solution, at finer .stl resolutions (unlike the attached) the number of faces one needs to highlight becomes very tedious.
Are there alternative methods that are more efficient prior to or during the meshing steps?
